Some scientists who study Mars also study Northern Arizona. That’s because our lava fields and water-carved canyons are similar to Martian terrain. It’s a good place to test out whether future colonists on Mars would be able to build houses out of local materials. That’s what astronomer Antonio Paris of St. Petersburg College in Florida is doing. He’s traveling the Colorado Plateau collecting soil samples to see if they’ll make good cement. He told KNAU’s Melissa Sevigny, if works here, it might also work on Mars.

About 30 miles northeast of Flagstaff in a remote area of high desert, is a set of manmade craters blasted into an ancient lava flow. They were put there 50 years ago as a training site for astronauts preparing to walk and drive on the moon.
